Application filed May 18,

T 0 all whom it may concern:

Be it known that I, EUGENE F. Nissan, a citizen of the United States,residing at Alameda, in the county of Alameda and State of California.have invented a new and useful Improvement in Envelope Fas' teners, ofwhich the following is a specification.

This application relates to a fastener, particularly adapted to be usedupon envelopes and like containers.

It is the principal object of the present invention to provide ametallic fastener which may be firmly secured to a sheet of materialsuch as the body panel of ,an envelope in a manner to prevent the readyremoval of the fastener by unauthorized persons, said fastener carryingtongues adapted to extend through the eyelet of an envelope flap and tobe thereafter separated to hold the flap in position and to permit a waxseal to be easily applied in a manner to completely conceal the tonguesand the fastening? element.

The present invention contemplates the use of a fastener being pressedfrom a single piece of thin sheet metal to form a diskshaped body havinga plurality of pointed tangs arranged around its periphery to be bentoutwardly after having passed through a sheet of material and othertangs in the body of the disk adapted to be bent inwardly, said diskbeing further formed with a pair of tongues which may be passed throughan envelope eyelet.

The invention is illustrated by Way of example in the accompanyingdrawings, in which:

Figure 1 is a view in perspective illustrating the fastener in positionto be applied to an, envelope.

Fig. 2 is a view in perspective illustrating the positions of thevarious tangs after the fastener has been applied to them.

Fig. 3 is a view in elevation showing the fragmentary portion of anenvelope with the fastener applied thereto, and drawn on an enlargedscale.

In the drawings, 10 indicates a body plate preferably formed from thingauge metal to provide a circular disk of small dimensions. Formedintegral with the plate and extending radially from the circumferencethereof is a plurality of tangs 11. These tangs are pointed and whenbent downwardly as indicated in Fig. 1 may be readily 1920. Serial No.332,431.

passed througha sheetof material to which the fastener is secured.WVhen-the fastener is blanked out, it is preferable that eight marginaltangs shall be formed. However, after the operation is completed two ofthese tangs extend from the ends of fastening' tongues 12. These tonguesextend from points near the center of the plate 10 and may be bent up asshown in Fig. 2 so that they may be passed through an opening or eyelet13 formed upon an envelope flap. A pair of tangs 14 are also struck fromthe disk 10 and through the body thereof. In providing the two sets oftangs 11 and 14, it is intended that they shall be both passed throughthe same sheet of material and that the tangs 11 shall be bent outwardlyto assume positions in radial alignment with the disk 10, while thetangs 14 are bent inwardly to extend radially and toward the center ofthe disk. arrangement it will be practically impossible for persons toremove or replace the fastener in an effort to reach the contents of theenvelope without detection. After the fastener has thus been secured toa sheet of material the tongues 12 may be bent upwardly as shown in Fig.2 so that they may be used to secure an envelope flap in position asshown in Fig. 3.

The flap may thereafter be sealed by completely covering the arearepresented by the fastener and thereby insuring that the fastener shallnever be molested without detection. It will thus be seen that thefastener here disclosed, while simple in construction and readilymanufactured may be so applied to an envelope or other sheet of materialas to be firmly held in position without possibility of removal withouthaving some sign by which the tampering would be detected.

While I have shown the preferred form of my invention as now known tome, it will be understood that various changes in the construction,combination and arrangement of parts may be made by those skilled in theart without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. An envelope fastener including a disk having radial outwardlyprojecting peripheral points, foldable outwardly, other points formedwithin the periphery and Due to this foldable inwardly; and alignedstrips cut from the body of the disk having points extending outwardlybeyond the peripheral edges of the disk, and foldable thereon.

2. An envelope fastener comprising a disk having spaced pointsprojecting from its periphery and foldable outwardly, other points outwithin the body of the disk and foldable towards the center from theirpoints of attachment; and stripsseparated from the body,extending inopposite directi0ns, with points beyond the edges of the disk, andfoldable to secure an envelope flap. r p
